29, 2004, by and among ATP OIL & GAS CORPORATION, a Texas corporation (the “Company”), and each holder of Warrants (as defined below) who is or may from time to time become a party hereto (collectively, the
“Holders”). 
  
 WHEREAS, in connection
with the execution and delivery of the Second Lien Credit Agreement (the “Second Lien Credit Agreement”) dated as of the date hereof, among the Company, the lenders from time to time party thereto and Credit Suisse First

that if the Company does not register any securities with respect to which it had given written notice of its intention to register to Holders, notwithstanding anything to the contrary in the foregoing, all of the costs incurred by the Holders in
connection with such registration shall be deemed to be Registration Expenses.

 ARTICLE II 
  
 Registration Under the Securities Act 
  
 Section 2.01. Demand Registration. (a) Right to Demand Registration. Subject to Section 2.01(c), at any time and from time to time, the
Majority Holders shall have the right to request in writing that the Company register the resale of all or part of the Holders’ Registrable Securities (a “Request”) (which Request shall specify the amount of Registrable
Securities intended to be disposed of by such requesting Holders and the intended method of disposition thereof) by filing with the SEC a Demand Registration Statement. As promptly as practicable, but no later than 15 days after receipt of a
Request, the Company shall give written notice of such requested registration to all other Holders of Registrable Securities. Subject to Section 2.01(b), the Company shall include in a Demand Registration (i) the Registrable Securities intended to
be disposed of by the Initiating Holders and (ii) the Registrable Securities intended to be disposed of by any other Holder which shall have made a written request (which request shall specify the amount of Registrable Securities intended to be
disposed of by the requesting Holder and the intended method of disposition thereof) to the Company for inclusion thereof in such registration within 20 days after the receipt of such written notice from the Company. The Company shall, as
expeditiously as possible, following a Request, use commercially reasonable efforts to cause to be filed with the SEC a Demand Registration Statement providing for the registration under the Securities Act of the resale of the Registrable Securities
which the Company has been so requested to register by all such Holders, to the extent necessary to permit the disposition of such Registrable Securities in accordance with the intended methods of disposition thereof specified in such Request or
further requests (including, without limitation, by means of a shelf registration pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) registering the resale from time to time by the Holders thereof of all
of the Registrable Securities upon and following the exercise from time to time of the Warrants, if so 

  

 5 








 
requested and if the Company is then eligible to use such a registration method). The Company shall use its reasonable best efforts to have such Demand
Registration Statement declared effective by the SEC as soon as practicable thereafter and to keep such Demand Registration Statement continuously effective for the period specified in Section 4.01(b). A Request may be withdrawn prior to the filing
of the Demand Registration Statement by the Majority Holders of the Registration (a “Withdrawn Request”) and a Demand Registration Statement may be withdrawn prior to the effectiveness thereof by the Majority Holders of the
Registration (a “Withdrawn Demand Registration”), and such withdrawals shall be treated as a Demand Registration which shall have been effected pursuant to this Section 2.01, unless the Holders of Registrable Securities the
resale of which was to be registered under such Registration Statement reimburse the Company for its reasonable out-of-pocket Registration Expenses relating to the preparation and filing of such Demand Registration Statement (to the extent actually
incurred), in which case such withdrawal shall not be treated as a Demand Registration effected pursuant to this Section 2.01 (and shall not be counted toward the number of Demand Registrations); provided, however, that if a Withdrawn
Request or Withdrawn Registration Statement is made (A) because of a material adverse change in the business, financial condition or prospects of the Company, or (B) because the sole or lead managing Underwriter advises that the amount of
Registrable Securities to be sold in such offering be reduced pursuant to Section 2.01(b) by more than 15% of the Registrable Securities the resale of which was to be registered under such Registration Statement, then such withdrawal shall not be
treated as a Demand Registration effected pursuant to this Section 2.01 (and shall not be counted toward the number of Demand Registrations), and the Company shall pay all Registration Expenses in connection therewith. Any Holder requesting
inclusion in a Demand Registration may, at any time prior to the effective date of the Demand Registration Statement (and for any reason) revoke such request by delivering written notice to the Company revoking such requested inclusion. 

 
 The registration rights granted pursuant to the provisions of this Section
2.01 shall be in addition to the registration rights granted pursuant to the other provisions of Article II hereof. 
  
 (b) Priority in Demand Registrations. If a Demand Registration involves an Underwritten Offering, and the sole or lead managing Underwriter, as the
case may be, of such Underwritten Offering shall advise the Company in writing (with a copy to each Holder requesting registration) on or before the date five days prior to the date then scheduled for such offering that, in its opinion, the amount
of Registrable Securities requested to be included in such Demand Registration exceeds the number which can be sold in such offering within a price range acceptable to the Majority Holders of the Registration (such writing to state the basis of such
opinion and the approximate number of Registrable Securities which, in the opinion of such Underwriter, may be included in such offering without causing the price to be below the bottom of such price range), and the Request is not thereafter
withdrawn, the Company shall include in such Demand Registration, to the extent of the number which the Company is so advised may be included in such offering, the Registrable Securities requested to be included in the Demand Registration by the
Holders allocated pro rata in proportion to 

  

 6 








 
the number of Registrable Securities requested to be included in such Demand Registration by each of them. In the event the Company shall not, by virtue of
this Section 2.01(b), include in any Demand Registration all of the Registrable Securities of any Holder requested to be included in such Demand Registration, such Holder may, upon written notice to the Company given within five days of the time
such Holder first is notified of such matter, further reduce the amount of Registrable Securities it desires to have included in such Demand Registration, whereupon only the Registrable Securities, if any, that it desires to have included will be so
included and the Holders not so reducing shall be entitled to a corresponding pro rata increase in the amount of Registrable Securities to be included in such Demand Registration. 
  
 (c) Limitations on Registrations. The rights of Holders of Registrable Securities to request Demand Registrations
pursuant to Section 2.01(a) are subject to the following limitations: (i) in no event shall the Company be required to effect a Demand Registration after March 29, 2010 and (ii) in no event shall the Company be required to effect, in the aggregate,
more than three Demand Registrations pursuant to this Section 2.01; provided, however, that such number shall be increased to the extent the Company (x) does not include in what would otherwise be the final registration for which the
Company is required to pay Registration Expenses the number of Registrable Securities requested to be registered by the Holders by reason of Section 2.01(b) or (y) terminates a Shelf Registration pursuant to Section 2.03 prior to the time that all
Registrable Securities covered by such Shelf Registration have been sold. 
  
 (d) Underwriting; Selection of Underwriters. Notwithstanding anything to the contrary contained in Section 2.01(a), if the Initiating Holders holding a majority of the Registrable Securities for which
registration was requested in the Request so elect, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of a firm commitment Underwritten Offering and such Initiating Holders may require that all
persons (including other Holders) participating in such registration sell their Registrable Securities to the Underwriters at the same price and on the same terms of underwriting applicable to the Initiating Holders. If any Demand Registration
involves an Underwritten Offering, the sole or managing Underwriter and any additional investment bankers and managers to be used in connection with such registration shall be selected by the Company subject to the approval of the Initiating Holders
holding a majority of the Registrable Securities for which registration was requested in the Request (such approval not to be unreasonably withheld or delayed). 
  

(e) Effective Registration Statement; Suspension. A Demand Registration Statement shall not be deemed to have become effective (and the related
registration will not be deemed to have been effected) (i) unless it has been declared effective by the SEC and remains effective in compliance with the provisions of the Securities Act with respect to the disposition of all Registrable Securities
covered by such Demand Registration Statement for the time period specified in Section 4.01(b); (ii) if the offering of any Registrable Securities pursuant to such Demand Registration Statement is unable to proceed as a result of any stop order,
injunction or other order or requirement of the SEC or any other governmental agency or court; or (iii) if, in the case of an Underwritten Offering, the conditions to closing specified in an underwriting agreement 

  

 7 








 
to which the Company is a party are not satisfied (other than by the sole reason of any breach or failure by the Holders of Registrable Securities) and are
not otherwise waived. 
  
 (f) Registration of Other
Securities. Whenever the Company shall effect a Demand Registration, no securities other than the Registrable Securities shall be covered by such registration unless the Majority Holders of the Registration shall have consented in writing to the
inclusion of such other securities (which consent shall not be unreasonably withheld). 
  
 (g) Registration Statement Form. Registrations under this Section 2.01 shall be on such appropriate registration form of the SEC (i) as shall be reasonably selected by the Company, and (ii) which shall be
available for the sale of Registrable Securities in accordance with the intended method or methods of disposition specified in the requests for registration. The Company agrees to include in any such Registration Statement all information which any
selling Holder, upon advice of counsel, shall reasonably request. 
  
 (h) Other Registrations. During the period (i) beginning on the date of a Request and (ii) ending on the date that is 90 days after the date that a Demand Registration Statement filed pursuant to such Request has been declared
effective by the SEC or, if the Holders shall withdraw such Request or such Demand Registration Statement, on the date of such Withdrawn Request or such Withdrawn Registration Statement, the Company shall not, without the consent of the Majority
Holders of the Registration, file a registration statement pertaining to any other securities of the Company. 
  
 Section 2.02. Incidental Registration. (a) Right to Include Registrable Securities. If the Company at any time or from time to time proposes
to register the sale of any of its securities under the Securities Act (other than in a registration on Form S-4 or S-8 or any successor form to such forms and other than pursuant to Section 2.01 or 2.03) whether or not pursuant to registration
rights granted to other holders of its securities and whether or not for sale for its own account, the Company shall deliver prompt written notice (which notice shall be given at least 15 days prior to such proposed registration) to all Holders of
Registrable Securities of its intention to undertake such registration, describing in reasonable detail the proposed registration and distribution (including the anticipated range of the proposed offering price, the class and number of securities
proposed to be registered and the distribution arrangements) and of such Holders’ right to participate in such registration under this Section 2.02 as hereinafter provided. Subject to the other provisions of this paragraph (a) and Section
2.02(b), upon the written request of any Holder made within 15 days after the receipt of such written notice (which request shall specify the amount of Registrable Securities intended to be disposed of by the requesting Holder and the intended
method of disposition thereof), the Company shall effect the registration under the Securities Act of the resale of all Registrable Securities requested by Holders to be so registered (an “Incidental Registration”), to the
extent required to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered, by inclusion of such Registrable Securities in the Registration Statement which covers the


  

 8 








 
securities which the Company proposes to register and shall cause such Registration Statement to become and remain effective with respect to such Registrable
Securities in accordance with the registration procedures set forth in Article IV hereof. If an Incidental Registration involves an Underwritten Offering, promptly after notification to the Company from the Underwriter of the price at which such
securities are to be sold, the Company shall so advise each participating Holder. The Holders requesting inclusion in an Incidental Registration may, at any time prior to the effective date of the Incidental Registration Statement (and for any
reason), revoke such request by delivering written notice to the Company revoking such requested inclusion. If at any time after giving written notice of its intention to register the sale of any securities and prior to the effective date of the
Incidental Registration Statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such sale, the Company may, at its election, give written notice of such
determination to each Holder of Registrable Securities and, thereupon, (A) in the case of a determination not to register, the Company shall be relieved of its obligation to register the resale of any Registrable Securities in connection with such
registration (but not from its obligation to pay the Registration Expenses incurred in connection therewith), without prejudice, however, to the rights of Holders to cause such registration to be effected as a registration under Section 2.01 or
2.03(a) and (B) in the case of a determination to delay such registration, the Company shall be permitted to delay the registration of the resale of such Registrable Securities for the same period as the delay in registering the sale of such other
securities; provided, however, that if such delay shall extend beyond 120 days from the date the Company received a request to include Registrable Securities in such Incidental Registration, then the Company shall again give all
Holders the opportunity to participate therein and shall follow the notification procedures set forth in the preceding paragraph. There is no limitation on the number of such Incidental Registrations pursuant to this Section 2.02 which the Company
is obligated to effect. 
  
 The registration rights granted
pursuant to the provisions of this Section 2.02 shall be in addition to the registration rights granted pursuant to the other provisions of Article II hereof. 
  

(b) Priority in Incidental Registration. If an Incidental Registration involves an Underwritten Offering (on a firm commitment basis), and the
sole or the lead managing Underwriter, as the case may be, of such Underwritten Offering shall advise the Company in writing (with a copy to each Holder requesting registration) on or before the date five days prior to the date then scheduled for
such offering that, in its opinion, the amount of securities (including Registrable Securities) requested to be included in such registration exceeds the amount which can be sold in such offering without materially interfering with the successful
marketing of the securities being offered (such writing to state the basis of such opinion and the approximate number of such securities which may, in the opinion of such Underwriter, be included in such offering without such effect), the Company
shall include in such registration, to the extent of the number which the Company is so advised may be included in such offering without such effect, (i) in the case of a registration initiated by the Company, (A) first, the securities that the
Company proposes to register for its own account, (B) second, the Registrable Securities requested to be included in such registration by the Holders, allocated pro rata in 

  

 9 








 
proportion to the number of Registrable Securities requested to be included in such registration by each of them, and (C) third, other securities of the
Company to be registered on behalf of any other person, and (ii) in the case of a registration initiated by a person other than the Company, (A) first, the securities requested to be included in such registration by any persons initiating such
registration, (B) second, the Registrable Securities requested to be included in such registration by the Holders and securities requested to be included by any other persons (not including Affiliates of the Company), allocated pro rata in
proportion to the number of securities requested to be included in such registration by each of them, and (C) third, the securities that the Company proposes to register for the account of it and its Affiliates, provided, however, that
in the event the Company will not, by virtue of this Section 2.02(b), include in any such registration all of the Registrable Securities of any Holder requested to be included in such registration, such Holder may, upon written notice to the Company
given within three days of the time such Holder first is notified of such matter, reduce the amount of Registrable Securities it desires to have included in such registration, whereupon only the Registrable Securities, if any, it desires to have
included will be so included and the Holders not so reducing shall be entitled to a corresponding pro rata increase in the amount of Registrable Securities to be included in such registration. 
  
 Section 2.03. S-3 Registration; Shelf Registration. (a) S-3
Registration. If at any time (i) the Majority Holder(s) request that the Company file a registration statement on S-3 or any successor form thereto registering the resale from time to time by the Holders of all of the Registrable Securities upon
and following the exercise from time to time of the Warrants, and (ii) the Company is a registrant entitled to use S-3 or any successor form thereto to register the resale of such securities, then the Company shall, as expeditiously as possible
following such Request, use commercially reasonable efforts to register under the Securities Act on S-3 or any successor form thereto, for public sale in accordance with the intended methods of disposition specified in such Request or any subsequent
requests (including, without limitation, by means of a Shelf Registration) the resale of all of the Registrable Securities; provided, that if such registration is for an Underwritten Offering, the terms of Sections 2.01(b) and 2.01(d)
shall apply (and any reference to “Demand Registration” therein shall, for purposes of this Section 2.03, instead be deemed a reference to “S-3 Registration”). Whenever the Company is required by this Section 2.03 to use
commercially reasonable efforts to effect the registration of the resale of Registrable Securities, each of the procedures and requirements of Section 2.01(a) and 2.01(e) (including but not limited to the requirements that the Company (A) notify all
Holders of Registrable Securities from whom such Request for registration has not been received and provide them with the opportunity to participate in the offering and (B) use commercially reasonable efforts to have such S-3 Registration Statement
declared and remain effective for the time period specified herein) shall apply to such registration (and any reference in such Sections 2.01(a) and 2.01(e) to “Demand Registration” shall, for purposes of this Section 2.03, instead be
deemed a reference to “S-3 Registration”). Notwithstanding anything to the contrary contained herein, no Request may be made under this Section 2.03 within 90 days after the effective date of a Registration Statement filed by the Company
covering a firm commitment Underwritten Offering in which the Holders of Registrable Securities shall have been entitled to join pursuant to this Agreement in which there shall have been effectively 

  

 10 








 
registered all Registrable Securities as to which registration shall have been requested. There is no limitation on the number of S-3 Registrations that the
Company is obligated to effect. 
  
 The Company shall include as
selling securityholders under the S-3 Registration Statement all Holders of Registrable Securities who request in accordance with the procedures herein to be so included, and (by filing a prospectus supplement or supplements, if required by law or
SEC rules) such other Holders of Registrable Securities that so request from time to time after the effectiveness of such S-3 Registration Statement, in each case after such Holder provides to the Company such information as the Company shall
request in accordance with Section 4.02. 
  
 The registration
rights granted pursuant to the provisions of this Section 2.03(a) shall be in addition to the registration rights granted pursuant to the other provisions of this Article II; provided, however, that if a S-3 Registration Statement has
been filed and is effective with respect to any Registrable Securities, the Company may satisfy its obligations with respect to a demand registration with respect to such Registrable Securities by utilizing such S-3 Registration Statement if the
offer and sale of such Registrable Securities can be accomplished thereunder. 
  
 (b) Shelf Registration. If a request made pursuant to Section 2.01 or 2.03(a) is for a Shelf Registration, the Company shall use commercially reasonable efforts to keep the Shelf Registration continuously
effective through the date on which all of the Registrable Securities covered by such Shelf Registration may be sold pursuant to Rule 144(k) under the Securities Act (or any successor provision having similar effect); provided,
however, that prior to the termination of such Shelf Registration, the Company shall first furnish to each Holder of Registrable Securities participating in such Shelf Registration (i) an opinion, in form and substance reasonably satisfactory
to the Majority Holders of the Registration, of counsel for the Company reasonably satisfactory to the Majority Holders of the Registration stating that such Registrable Securities are freely saleable pursuant to Rule 144(k) under the Securities Act
(or any successor provision having similar effect) or (ii) a “No-Action Letter” from the staff of the SEC stating that the SEC would not recommend enforcement action if the Registrable Securities included in such Shelf Registration were
sold in a public sale other than pursuant to an effective registration statement. 
  
 Section 2.04. Underwritten Offerings. (a) Demand Underwritten Offerings. If requested by the sole or lead managing Underwriter for any Underwritten Offering effected pursuant to a Demand Registration or
S-3 Registration, the Company shall enter into a customary underwriting agreement with the Underwriters for such offering, such agreement to be reasonably satisfactory in substance and form to the Company and each Holder of Registrable Securities
participating in such offering and to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of that type, including, without limitation, indemnification and contribution to the
effect and to the extent provided in Article V hereof. 
  

 11 








 (b) Holders of Registrable Securities to be Parties to Underwriting Agreement. The Holders of
Registrable Securities to be distributed by Underwriters in an Underwritten Offering contemplated by Article II hereof shall be parties to the underwriting agreement between the Company and such Underwriters and may, at such Holders’ option,
require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such Underwriters shall also be made to and for the benefit of such Holders of Registrable Securities
and that any or all of the conditions precedent to the obligations of such Underwriters under such underwriting agreement be conditions precedent to the obligations of such Holders of Registrable Securities; provided, however, that the
Company shall not be required to make any representations or warranties with respect to written information specifically provided by a selling Holder for inclusion in the Registration Statement. No Holder shall be required to make any
representations or warranties to, or agreements with, the Company or (in the case of an Incidental Registration) the Underwriters other than representations, warranties or agreements regarding such Holder, such Holder’s Registrable Securities
and such Holder’s intended method of disposition. 
  
 (c)
Participation in Underwritten Registration. Notwithstanding anything herein to the contrary, no person may participate in any Underwritten Offering hereunder unless such person (i) agrees to sell its securities on the same terms and
conditions provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangement and (ii) accurately completes and executes in a timely manner all questionnaires, powers of attorney, indemnities, custody
agreements, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 
  
 Section 2.05. Expenses. Except as stated herein, the Company shall pay all Registration Expenses in connection with any Demand Registration,
Incidental Registration or S-3 Registration or Shelf Registration whether or not such registration shall become effective and whether or not all Registrable Securities originally requested to be included in such registration are withdrawn or
otherwise ultimately not included in such registration, except as otherwise provided with respect to a Withdrawn Request and a Withdrawn Demand Registration in Section 2.01(a). 
  
 Section 2.06. Postponements. The Company shall be entitled to postpone a Demand Registration and S-3 Registration and
to require the Holders of Registrable Securities to discontinue the disposition of their securities covered by a Shelf Registration during any Blackout Period (as defined below) (i) if the Board of Directors of the Company determines in good faith
that effecting such a registration or continuing such disposition at such time would have a material adverse effect upon a proposed sale of any substantial portion of the assets of the Company or a proposed material acquisition of assets by the
Company or a merger, reorganization, recapitalization or similar current transaction materially affecting the capital structure or equity ownership of the Company, or (ii) if the Company is otherwise in possession of material information which the
Board of Directors of the Company determines in good faith it is not in the best interests of the Company to disclose in a registration statement at such time; provided, however, that the Company may only delay a Demand Registration or
S-3 Registration pursuant to this 

  

 12 








 
Section 2.06 by delivery of a Blackout Notice (as defined below) within 10 days of delivery of the request for such Registration under Section 2.01 or
Section 2.03, as applicable, and may delay a Demand Registration or S-3 Registration and require the Holders of Registrable Securities to discontinue the disposition of their securities covered by a Shelf Registration only for a reasonable period of
time not to exceed 45 days (or such earlier time as the applicable transaction is consummated or no longer proposed or the material information has been made public) (the “Blackout Period”). There shall not be more than one
Blackout Period in any 12 month period. The Company shall promptly notify the Holders in writing (a “Blackout Notice”) of any decision to postpone a Demand Registration or S-3 Registration or to discontinue sales of
Registrable Securities covered by a Shelf Registration pursuant to this Section 2.06 and shall include a general statement of the reason for such postponement, an approximation of the anticipated delay and an undertaking by the Company promptly to
notify the Holders as soon as a Demand Registration or S-3 Registration may be effected or sales of Registrable Securities covered by a Shelf Registration may resume. In making any such determination to initiate or terminate a Blackout Period, the
Company shall not be required to consult with or obtain the consent of any Holder, and any such determination shall be the Company’s sole responsibility. Each Holder shall treat all notices received from the Company pursuant to this Section
2.06 in the strictest confidence and shall not disseminate such information. If the Company shall postpone the filing of a Demand Registration Statement or an S-3 Registration Statement, the Majority Holders who were to participate therein shall
have the right to withdraw the request for registration. Any such withdrawal shall be made by giving written notice to the Company within 10 days after receipt of the Blackout Notice. Such withdrawn registration request shall not be treated as a
Demand Registration effected pursuant to Section 2.01 (and shall not be counted towards the number of Demand Registrations effected pursuant to Section 2.01(c)), and the Company shall pay all Registration Expenses in connection therewith.

  
 ARTICLE III 
  
 Holdback Arrangements 
  
 Section 3.01. Restrictions on Sale by Holders of Registrable Securities. Each Holder of Registrable Securities
agrees, by acquisition of such Registrable Securities, if timely requested in writing by the sole or lead managing Underwriter, not to make any short sale of, loan, grant any option for the purchase of or effect any sale or distribution, of any of
the Company’s equity securities (or any security convertible into or exchangeable or exercisable for any of the Company’s equity securities) during the nine business days (as such term is used in Regulation M under the Exchange Act) prior
to, and during the time period reasonably requested by the sole or lead managing Underwriter not to exceed 90 days, beginning on the effective date of the applicable registration statement (except as part of such Underwritten Offering or pursuant to
registrations on Forms S-4 or S-8 or any successor form to such forms), unless the sole or lead managing Underwriter in such Underwritten Offering otherwise agrees. 
  

 13 








 Section 3.02. Restrictions on Sale by the Company and Others. The Company agrees that if timely
requested in writing by the sole or lead managing Underwriter in an Underwritten Offering of any Registrable Securities, not to make any short sale of, loan, grant any option for the purchase of or effect any sale or distribution of any of the
Company’s equity securities (or any security convertible into or exchangeable or exercisable for any of the Company’s equity securities) during the nine business days (as such term is used in Regulation M under the Exchange Act) prior to,
and during the time period reasonably requested by the sole or lead managing Underwriter not to exceed 90 days, beginning on the effective date of the applicable registration statement (except as part of such Underwritten Offering or pursuant to
registrations on Forms S-4 or S-8 or any successor form to such forms), unless the sole or lead managing Underwriter in such Underwritten Offering otherwise agrees. The Company will use its reasonable best efforts to cause each director or officer
of the Company and each holder of 5% or more of the equity securities (or any security convertible into or exchangeable or exercisable for any of its equity securities) of the Company purchased from the Company at any time after the date of this
Agreement (other than in a registered public offering or in a public sale) to so agree. 
  
 ARTICLE IV 
  
 Registration Procedures. 
  
 Section 4.01. Obligations of the Company. Whenever the Company is required to effect the registration of Registrable Securities under the
Securities Act pursuant to Article II of this Agreement, the Company shall use commercially reasonable efforts to, as expeditiously as practicable: 
  
 (a) prepare and file with the SEC (promptly, and in any event within 60 days after receipt of a request to register Registrable
Securities) the requisite Registration Statement to effect such registration, which Registration Statement shall comply as to form in all material respects with the requirements of the applicable form and include all financial statements required by
the SEC to be filed therewith, and the Company shall use commercially reasonable efforts to cause such Registration Statement to become effective (provided, that the Company may discontinue any registration of its securities that are not
Registrable Securities, and, under the circumstances specified in Section 2.02, its securities that are Registrable Securities); provided, however, that before filing a Registration Statement or Prospectus or any amendments or
supplements thereto, or comparable statements under securities or blue sky laws of any jurisdiction, the Company shall (i) provide Holders’ Counsel and any other Inspector (as defined below) with an adequate and appropriate opportunity to
participate in the preparation of such Registration Statement and each Prospectus included therein (and each amendment or supplement thereto or comparable statement) to be filed with the SEC, which documents shall be subject to the review and
comment of Holders’ Counsel, and (ii) not file any such Registration Statement or Prospectus (or amendment or supplement thereto or comparable statement) with the SEC to which Holder’s Counsel, any selling Holder or any other Inspector
shall have 

  

 14 








 
reasonably objected on the grounds that such filing does not comply in all material respects with the requirements of the Securities Act or of the rules or
regulations thereunder; 
  
 (b) prepare and file
with the SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary (i) to keep such Registration Statement effective during the periods required herein, and (ii) to comply
with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement, in each case until such time as all of such Registrable Securities have been disposed of in accordance
with the intended methods of disposition by the seller(s) thereof set forth in such Registration Statement; provided that except with respect to any Shelf Registration, such period need not extend beyond twelve months after the effective date
of the Registration Statement; and provided further, that with respect to any Shelf Registration, such period need not extend beyond the time period provided in Section 2.03, and which periods, in any event, shall terminate when all
Registrable Securities covered by such Registration Statement have been sold or have otherwise ceased to be Registrable Securities (but not before the expiration of the applicable period referred to in Section 4(3) of the Securities Act and Rule 174
thereunder, if applicable); 
  
 (c) furnish,
without charge, to each selling Holder of such Registrable Securities and each Underwriter, if any, of the securities covered by such Registration Statement, such number of copies of such Registration Statement, each amendment and supplement thereto
(in each case including all exhibits), and the Prospectus included in such Registration Statement (including each preliminary Prospectus) in conformity with the requirements of the Securities Act, and other documents, as such selling Holder and
Underwriter may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities owned by such selling Holder (the Company hereby consenting to the use in accordance with applicable law of each such
Registration Statement (or amendment or post-effective amendment thereto) and each such Prospectus (or preliminary prospectus or supplement thereto) by each such selling Holder of Registrable Securities and the Underwriters, if any, in connection
with the offering and sale of the Registrable Securities covered by such Registration Statement or Prospectus); 
  
 (d) prior to any public offering of Registrable Securities, use commercially reasonable efforts to register or qualify all Registrable
Securities and other securities covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions as any selling Holder of Registrable Securities covered by such Registration Statement or the sole or lead
managing Underwriter, if any, may reasonably request to enable such selling Holder to consummate the disposition in such jurisdictions of the Registrable Securities owned by such selling Holder and to continue such registration or qualification in
effect in each such jurisdiction for as long as such Registration 

  

 15 








 
Statement remains in effect (including through new filings or amendments or renewals), and do any and all other acts and things which may be necessary or
advisable to enable any such selling Holder to consummate the disposition in such jurisdictions of the Registrable Securities owned by such selling Holder; provided, however, that the Company shall not be required to consent to general
service of process in any such jurisdiction; 
  
 (e) use commercially reasonable efforts to obtain all other approvals, consents, exemptions or authorizations from such governmental agencies or authorities as may be necessary to enable the selling Holders of such Registrable Securities to
consummate the disposition of such Registrable Securities; 
  
 (f) notify Holders’ Counsel, each Holder of Registrable Securities covered by such Registration Statement and the sole or lead managing Underwriter, if any: (i) when the Registration Statement, any pre-effective
amendment, the Prospectus or any prospectus supplement related thereto or post-effective amendment to the Registration Statement has been filed and, with respect to the Registration Statement or any post-effective amendment, when the same has become
effective, (ii) of any request by the SEC or any state securities or blue sky authority for amendments or supplements to the Registration Statement or the Prospectus related thereto or for additional information, (iii) of the issuance by the SEC of
any stop order suspending the effectiveness of the Registration Statement or the initiation or threat of any proceedings for that purpose, (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of
any Registrable Securities for sale under the securities or blue sky laws of any jurisdiction or the initiation of any proceeding for such purpose, (v) of the existence of any fact of which the Company becomes aware or the happening of any event
which results in (A) the Registration Statement containing an untrue statement of a material fact or omitting to state a material fact required to be stated therein or necessary to make any statements therein not misleading, or (B) the Prospectus
included in such Registration Statement containing an untrue statement of a material fact or omitting to state a material fact required to be stated therein or necessary to make any statements therein, in the light of the circumstances under which
they were made, not misleading, (vi) if at any time the representations and warranties contained in any underwriting agreement in respect of such offering cease to be true and correct in all material respects, and (vii) of the Company’s
reasonable determination that a post-effective amendment to a Registration Statement would be appropriate or that there exists circumstances not yet disclosed to the public which make further sales under such Registration Statement inadvisable
pending such disclosure and post-effective amendment; and, if the notification relates to an event described in any of the clauses (ii) through (vii) of this Section 4.01(f), (1) each Holder agrees that such Holder will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s) covering such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated below or receipt of notice
that no supplement or amendment is required; provided, that nothing herein shall prevent any Holder, 

  

 16 








 
in connection with any sale of Registrable Securities with respect to which a Holder has entered into a contract for sale prior to the Holder’s receipt
of a notice from the Company hereunder and for which the Holder has not yet settled, from settling such sale and delivering unlegended shares, if applicable, and (2) the Company shall promptly prepare a supplement or post-effective amendment to such
Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that (1) such Registration Statement shall not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein not misleading, and (2) as thereafter delivered to the purchasers of the Registrable Securities being sold thereunder, such Prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein in the light of the circumstances under which they were made not misleading (and shall furnish to each
such Holder and each Underwriter, if any, a reasonable number of copies of such Prospectus so supplemented or amended); and if the notification relates to an event described in clause (iii) of this Section 4.01(f), the Company shall take all
reasonable action required to prevent the entry of such stop order or to remove it if entered; 
  
 (g) make available for inspection by any selling Holder of Registrable Securities, any sole or lead managing Underwriter participating in
any disposition pursuant to such Registration Statement, Holders’ Counsel and any attorney, accountant or other agent retained by any such seller or any Underwriter (each, an “Inspector” and, collectively, the
“Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company and any subsidiaries thereof as may be in existence at such time (collectively, the
“Records”) as shall be necessary, in the opinion of such Holders’ and such Underwriters’ respective counsel, to enable them to exercise their due diligence responsibility and to conduct a reasonable investigation
within the meaning of the Securities Act, and cause the Company’s and any subsidiaries’ officers, directors and employees, and the independent public accountants of the Company, to supply all information reasonably requested by any such
Inspectors in connection with such Registration Statement; 
  
 (h) if such registration involves an Underwritten Offering, obtain an opinion from the Company’s counsel and a “cold comfort” letter from the Company’s independent public accountants who have
certified the Company’s audited financial statements included or incorporated by reference in such Registration Statement, dated the date of the closing under the underwriting agreement), in customary form and covering such matters as are
customarily covered by such opinions and “cold comfort” letters delivered to underwriters in underwritten public offerings, which opinion and letter shall be reasonably satisfactory to the sole or lead managing Underwriter, and furnish to
each Underwriter a copy of such opinion and letter addressed to such Underwriter; 
  

 17

SEC and any other governmental agency or authority having jurisdiction over the offering, and make available to its security holders, as soon as reasonably practicable but no later than 90 days after the end of any 12-month period, an earnings
statement (i) commencing at the end of any month in which Registrable Securities are sold to Underwriters in an Underwritten Offering and (ii) commencing with the first day of the Company’s calendar month next succeeding each sale of
Registrable Securities after the effective date of a Registration Statement, which statement shall cover such 12-month periods, in a manner which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; 
  
 (k) use commercially reasonable efforts to cause all such
Registrable Securities to be duly included for quotation on the Nasdaq Stock Market’s National Market (the “Nasdaq National Market”) if the Company’s securities of such class are at the time included on the Nasdaq
National Market or listed on the principal national securities exchange on which the Company’s securities of such class are then listed, if applicable;

 (m) cooperate with each selling Holder of Registrable Securities and each Underwriter participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings
required to be made with the NASD and make reasonably available its employees and personnel and otherwise provide reasonable assistance to the Underwriters (taking into account the needs of the Company’s businesses and the requirements of the
marketing process) in the marketing of Registrable Securities in any Underwritten Offering; 
  
 (n) cooperate with the selling Holders of Registrable Securities and the sole or lead managing Underwriter, if any, to facilitate the
timely preparation and delivery of certificates not bearing any restrictive legends representing the Registrable Securities to be sold, and cause such Registrable Securities to be issued in such denominations and registered in such names in
accordance with the underwriting agreement prior to any sale of Registrable Securities to the Underwriters or, if not an Underwritten Offering, in accordance with the instructions of the selling Holders of Registrable Securities at least three
business days prior to any sale of Registrable Securities; 
  

 18 








 (o) keep each selling Holder of Registrable Securities advised in writing as to the
initiation and progress of any registration under Article II hereunder; 
  
 (p) upon written request, furnish to each Holder participating in the offering and the sole or lead managing Underwriter, if any, without charge, at least one manually-signed copy of the Registration Statement and any
post-effective amendments thereto, including financial statements and schedules, all documents incorporated therein by reference and all exhibits (including those deemed to be incorporated by reference); 
  
 (q) if requested by the sole or lead managing Underwriter or
any selling Holder of Registrable Securities, promptly incorporate in a prospectus supplement or post-effective amendment such information concerning such Holder of Registrable Securities, the Underwriters or the intended method of distribution as
the sole or lead managing Underwriter or the selling Holder of Registrable Securities reasonably requests to be included therein and as is appropriate in the reasonable judgment of the Company, including, without limitation, information with respect
to the number of shares of the Registrable Securities being sold to the Underwriters, the purchase price being paid therefor by such Underwriters and with respect to any other terms of the Underwritten Offering of the Registrable Securities to be

 Section 4.02.
Seller Information. The Company may require each selling Holder of Registrable Securities as to which any registration is being effected to furnish to the Company such information regarding such seller and the disposition of such securities
as the Company may from time to time reasonably request in writing; provided, however, that such information shall be used only in connection with such Registration. If any Registration Statement or comparable statement under
“blue sky” laws refers to any Holder by name or otherwise as the Holder of any securities of the Company, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such
Holder and the Company, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the Company’s securities covered thereby and that such holding does
not imply that such Holder will assist in meeting any future financial requirements of the Company, and (ii) in the event that such reference to such Holder by name or otherwise is not in the judgment of the Company, as advised by counsel, required
by the Securities Act or any similar federal statute or any state “blue sky” or securities law then in force, the deletion of the reference to such Holder. 
  

 19 








 Section 4.03. Notice to Discontinue. Each Holder of Registrable Securities agrees by acquisition
of such Registrable Securities that, (i) upon receipt of any notice from the Company of the happening of any event of the kind described in Section 4.01(f)(ii) through 4.01(f)(vii), such Holder shall forthwith discontinue disposition of Registrable
Securities pursuant to the Registration Statement covering such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 4.01(f) and, if so directed by the Company, such
Holder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the Prospectus covering such Registrable Securities which is current at the time of receipt of
such notice. If the Company shall give any such notice, the Company shall extend the period during which such Registration Statement shall be maintained effective pursuant to this Agreement (including, without limitation, the period referred to in
Section 4.01(b)) by the number of days during the period from and including the date of the giving of such notice pursuant to Section 4.01(f) to and including the date when the Holder shall have received the copies of the supplemented or amended
prospectus contemplated by and meeting the requirements of Section 4.01(f). 
  
 ARTICLE V 
  
 Indemnification;
Contribution 
  
 Section 5.01. Indemnification by the
Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Holder of Registrable Securities, its officers, directors, partners, members, shareholders, employees, Affiliates, advisers, attorneys and
agents (collectively, “Agents”) and each person who controls such Holder (within the meaning of the Securities Act) and its Agents with respect to each registration which has been effected pursuant to this Agreement, against
any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in respect thereof, and expenses (as incurred or suffered and including, but not limited to, any and all expenses incurred
in investigating, preparing or defending any litigation or proceeding, whether commenced or threatened, and the reasonable fees, disbursements and other charges of legal counsel) in respect thereof (collectively, “Claims”),
insofar as such Claims arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (including any preliminary, final or summary prospectus and any amendment or
supplement thereto) related to any such registration or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the
Securities Act or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, or any qualification or compliance incident thereto; provided,
however, that the Company will not be liable in any such case to the extent that any such Claims arise out of or are based upon any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material
fact so made in reliance upon and in conformity with written information furnished to the Company by a Holder, Underwriter or other indemnified person hereunder expressly for use therein. The Company shall also agree to 

  

 20 








 
indemnify any Underwriters of the Registrable Securities, their Agents and each person who controls any such Underwriter (within the meaning of the
Securities Act) to the same extent as provided above with respect to the indemnification of the Holders of Registrable Securities. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any
person who may be entitled to indemnification pursuant to this Article V and shall survive the transfer of securities by such Holder or Underwriter. 
  
 Section 5.02. Indemnification by Holders. Each Holder, if Registrable Securities held by it are included in the securities as to which a
registration is being effected, agrees to, severally and not jointly, indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors and officers, each other person who participates as an Underwriter in the offering
or sale of such securities and its Agents and each person who controls the Company against any and all Claims, insofar as such Claims arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any
Registration Statement or Prospectus (including any preliminary, final or summary prospectus and any amendment or supplement thereto) related to such registration, or any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by a Holder, Underwriter or other indemnified person hereunder expressly for use therein, or any violation by such Holder of the Securities Act or any rule or regulation thereunder applicable to such
Holder and relating solely to action or inaction solely caused by such Holder as required by such Holder in connection with any such registration, or any qualification or compliance incident thereto; provided, however, that the
aggregate amount which any such Holder shall be required to pay pursuant to this Section 5.02 shall in no event be greater than the amount of the net proceeds received by such Holder upon the sale of the Registrable Securities pursuant to the
Registration Statement giving rise to such Claims less all amounts previously paid by such Holder with respect to any such Claims. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any
person who may be entitled to indemnification pursuant to this Article V and shall survive the transfer of securities by such Holder or Underwriter. 
  
 Section 5.03. Conduct of Indemnification Proceedings. Promptly after receipt by an indemnified party of notice of any Claim or the commencement of
any action or proceeding involving a Claim under this Article V, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party pursuant to Article V, (i) notify the indemnifying party in writing of the
Claim or the commencement of such action or proceeding; provided, that the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its obligations under this Article V, except to the extent the
indemnifying party is materially and actually prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under this Article V, and (ii) permit such indemnifying party
to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any indemnified 

  

 21 








 
party shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at
the expense of such indemnified party unless (A) the indemnifying party has agreed in writing to pay such fees and expenses, (B) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory
to such indemnified party within 20 days after receiving notice from such indemnified party that the indemnified party believes it has failed to do so, or (C) in the reasonable judgment of any such indemnified party, based upon advice of counsel, a
conflict of interest shall exist between such indemnified party and the indemnifying party with respect to such claims; it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to no more than
one firm of local counsel) at any time for all such indemnified parties. No indemnifying party shall be liable for any settlement of any such claim or action effected without its written consent, which consent shall not be unreasonably withheld. No
indemnifying party shall, without the consent of the indemnified party, which consent shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement of any claim or action in respect of which indemnification or
contribution may be sought hereunder, unless such settlement, (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim, (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any indemnified party, and (3) does not provide for any action on the part of any party other than the payment of money damages which is to be paid in full by the indemnifying party. 
  
 Section 5.04. Contribution. If the indemnification provided for in
Section 5.01 or 5.02 from the indemnifying party for any reason is unavailable to (other than by reason of exceptions provided therein), or is insufficient to hold harmless an indemnified party hereunder in respect of any Claim, then the
indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Claim in such proportion as is appropriate to reflect the relative fault of the
indemnifying party, on the one hand, and the indemnified party, on the other hand, in connection with the actions which resulted in such Claim, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made
by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. If, however, the foregoing allocation
is not permitted by applicable law, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative faults but also the relative benefits of
the indemnifying party and the indemnified party as well as any other relevant equitable considerations.

regulation of any governmental authority, other than the Securities Act. The indemnity agreements contained herein shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or
contract. 
  
 Section 5.06. Indemnification Payments. The
indemnification and contribution required by this Article V shall be made by periodic payments of the amount thereof during the course of any investigation or defense, as and when bills are received or any expense, loss, damage or liability is

	ARTICLE	VI 

  
 General 
  
 Section 6.01.
Adjustments Affecting Registrable Securities. The Company agrees that it shall not effect or permit to occur any combination or subdivision of shares or other securities that would adversely affect the ability of the Holder of any Registrable
Securities to include such Registrable Securities in any registration contemplated by this Agreement or the marketability of such Registrable Securities in any such registration. 
  
 Section 6.02. Registration Rights to Others. The Company represents and warrants that it is not currently a party to
any agreement with respect to its securities granting registration rights to persons other than the Holders. If the Company shall at any time hereafter provide to any holder of any securities of the Company rights with respect to the registration of
the sale of such securities under the Securities Act (not including any such rights which have been previously granted), without the prior written consent of the Majority Holders, (i) such rights shall not be in conflict with or adversely affect any
of the rights provided in this Agreement to the Holders and (ii) if such rights are provided on terms or conditions more favorable to such holder than the terms and conditions provided in this Agreement, the Company shall provide (by way of
amendment to this Agreement or otherwise) such more favorable terms or conditions to the Holders. 
  
 Section 6.03. Availability of Information; Rule 144; Rule 144A; Other Exemptions. So long as the Company shall not have filed a registration
statement pursuant to Section 12 of the Exchange Act or a registration statement pursuant to the requirements of the Securities Act, the Company shall, at any time and from time to time, upon the request of any Holder of Registrable Securities and
upon the request of any person designated by such Holder as a prospective purchaser of any Registrable Securities (provided such person agrees to execute a customary confidentiality agreement relating to the Company’s nonpublic information),
furnish in writing to such Holder or such prospective purchaser, as the case may be, a statement as of a date not earlier than 12 months prior to the date of such request of the nature of the business of the Company 

  

 23 








 
and the products and services it offers and copies of the Company’s most recent balance sheet and profit and loss and retained earnings statements,
together with similar financial statements for the two preceding fiscal years, to the extent that the Company shall have been in operation for such time, all such financial statements to be audited to the extent audited statements are reasonable
available; provided that, in any event the most recent financial statements so furnished shall include a balance sheet as of a date less than 16 months prior to the date of such request, statements of profit and loss and retained earnings for
the 12 months preceding the date of such balance sheet, and, if such balance sheet is not as of a date less than 6 months prior to the date of such request, additional statements of profit and loss and retained earnings for the period from the date
of such balance sheet to a date less than 6 months prior to the date of such request. If the Company shall have filed a registration statement pursuant to the requirements of Section 12 of the Exchange Act or a registration statement pursuant to the
requirements of the Securities Act, the Company covenants that it shall timely file any reports required to be filed by it under the Securities Act or the Exchange Act (including, but not limited to, the reports under Sections 13 and 15(d) of the
Exchange Act referred to in subparagraph (c) of Rule 144 under the Securities Act), and that it shall take such further action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable
such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 and Rule 144A under the Securities Act, as such rules may be amended from time to time, or (ii)
any other rule or regulation now existing or hereafter adopted by the SEC. Upon the request of any Holder of Registrable Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements.

  
 Section 6.04. Amendments and Waivers. The provisions of
this Agreement, including the provisions of this sentence, may not be amended, modified, supplemented or terminated, and waivers or consents to departures from the provisions hereof may not be given, without the written consent of the Company and
the Majority Holders; provided, however, that no such amendment, modification, supplement, waiver or consent to departure shall reduce the aforesaid percentage of Registrable Securities without the written consent of all of the Holders
of Registrable Securities; and provided further, that nothing herein shall prohibit any amendment, modification, supplement, termination, waiver or consent to departure the effect of which is limited only to those Holders who have agreed to
such amendment, modification, supplement, termination, waiver or consent to departure.

validity, legality and enforceability of any such provision, paragraph, word, clause, phrase or sentence in every other respect and of the other remaining provisions, paragraphs, words, clauses, phrases or sentences hereof shall not be in any way
impaired, it being intended that all rights, powers and privileges of the parties hereto shall be enforceable to the fullest extent permitted by law. 
  
 Section 6.10. Jurisdiction; Consent to Service of Process. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for

relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in
such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement in the courts of any jurisdiction. 
  
 (b) Each of the parties hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may now or

 Section 6.12. Remedies; Specific Performance. The Company stipulates that there would be no adequate remedy at law to the Holders in the event of
any default or threatened default by the Company in the performance of or compliance with any of the terms of this Agreement and accordingly, the Company agrees that, in addition to any other remedy to which any Holder may be entitled at law or in
equity, the Holders shall be entitled to specific performance of the obligations of the Company under this Agreement, without the posting of any bond, in accordance with the terms and conditions of this Agreement in any court of the United States or
any State thereof having jurisdiction, and if any action should be brought in equity to enforce any of the provisions of this Agreement, the Company shall not raise the defense that there is an adequate remedy at law. Except as otherwise provided by
law, a delay or omission by any Holder in exercising any right or remedy accruing upon any such breach or threatened breach shall not impair the right or remedy or constitute a waiver of or acquiescence in any such breach. No remedy shall be
exclusive of any other remedy. All available remedies shall be cumulative. 
  
 Section 6.13. Entire Agreement. This Agreement and the Warrant Agreement are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, representations, warranties, covenants or undertakings relating to such subject matter, other than those set
forth or referred to herein or in the Warrant Agreement. This Agreement and the Warrant Agreement supersede all prior agreements

perform or cause to be done and performed all such further acts and things and shall execute and deliver all such other agreements, certificates, instruments and documents as any other party hereto reasonably may request in order to carry out the
